Specification of Letters Patent. Patented Deg, 18, 1917,

Application filed March 17, 1915. Serial No. 14,980.

To all whom itma'y concern;

Be it known that I, FRANK J. GILROY, a citizen of the United States,residing at Buf falo, in the county of Erie and State of New York, haveinvented certain new and useful Im rovements in Car-Doors, of which thefol owing is a specification, reference being had therein to theaccompanying drawing. I This invention relates to car doors which, whenshut, are in close engagement at allperipheral points with devices onthe car, and which normally rest uponrollers mounted upon the exteriorof the car, below the path of the door, in position to support the doorwhether in open or closed position. The objects are to provide aconstruction adaptable for'use with thin metal doors or with new or oldwooden doors; that obviates the necessity for internal boarding toprevent the escape of loose granular material with which the car maybeloaded; that fully excludes water; that will stand rough usage; thatcannot, open or closed, move outward from the car wall; and that isextremely simple and inexpensive.

In the accompanying drawings,

Figure 1 is a side elevation of a portion of a car provided with mynovel devices.

Figs. 2, 3, 4, 5,-6 are, respectively, sections on the lines 2-2, 3 3,6-6, Fig. 1.'

Fig. 7 is aovlew analogous toFig. 1 showing a smaller portion of a carprovided with a wooden door.

, Figs. 8, 9, 10,11 are sectional viewsshowing construction when awooden, door is used and corresponding to Figs. 2 3, 4, 5, respectively.v

- Fig. '12 is a horizontal section through a rear door-post andillustrates a modified construction.

Fig. 13 is a vertical section of the belt rail portion of the post ofFig. 12.

In these drawings, A represents the side wall of a car rovided with adoor having a body B of thin sheet steel reinforced at its forward edgeby a T-bar C, at its upper edge by a bar D, at its rear margin by anangle bar E, and at its lower edge by a channel bar. F made wide nearthe door angles and overlapped by the bars 0, E, to which it is rivetedor otherwise rigidly secured. Across the body of the door extendhorizontal T-bars G which, like the marginal. members just mentioned,are rigidly secured to the body B and, at their ends, to

the bars C, E, which they overlap. To the angle bar E is fixed a secondangle bariH, one flange H of which forms a hook parallel to and slightlywithin the 'plane' of the body B.

To the exterior of the car, below the plane of thecar floor I (Fig. 3 adoor-engaging member J is secured. This member is pro vided, along itsupper side, with a down wardly extending orhooked flange J with whichthe bar F on the door engages, and .belowthe hook the member extendsoutward beyond the plane of the door and is pro- -vided, below" the.edge of the door, with broad vertical openings in which are cylin-- 1drical rollers J mounted on shafts J and projecting slightly above theplane ofqthe outwardly extending portion of the member J, which isrigidly secured in place by bolts J passing through the member, the carsill .I', a strengthening bar I and a three web angle'bar I and alsofurther secured by rivets I, preferably,- as shown in Fig. 9.

.The upper side of thedoor is overlapped by a downwardly inclined anglebar K securedby bolts K passing through the upper portion of the carframe and like the member below extending rearwardly from the dooropeningso that when the door is fully opened its upper and lower marginsare still securely held close to the car wall.

The up or edge of this bar lies wholly below the oblique faceof a woodstrip K which prevents water from passing behind the bar. nThe forwardmargin of the door when the latter is'closed, as in Fig. 5, lies withinthe flange of a'braced member L secured by bolts L passing through thedoor post L and at the opposite edge ofthe door the flange assingthrough the be secured by ordinary devices with such safety devices asmay be selected.

.of the angle bar H engages the flange of an angle bar M forming a sortof j'amb-and secured by bolts M door post M and paral e1 to'the wall ofthe Nearly all parts of the door described a re of commercial steelobtainable everywhere, and

hence-its cost is "cry little more than the costof a wood door, or iseven lessif salvage on old doors be considered. It is however desirableto obtain similar advantages without discarding wood doors already inuse, and Figs. 7, S, 9. 10. 11 show modificationswhich may be used withwood doors. In these figures, 0 represents a wood door having itsforward and upper margins covered by angle bars 0 while its rear andlower edges are provided with channel bars 0 0 The front edge of theclosed door engages under a bar P similar to the bar Lof the primaryform, and the channel bar 0 engages a bar Q analogous to the bar M ofFig. 4. As in the other form, the door normally rests on rollers R,which in this instance however are mounted in separate brackets R,secured by bolts R passing through the car sill and a three-web anglebar member R to the lower flange of which the brackets are also riveted.The channel bar forms a smooth continuous surface, at the lower-edge ofthe door, to rest upon the rollers. In this case water is excluded fromthe inner face of the bar K by a thin metal sheet S, which may be ofcopper, o erlapping the upper flange of the bar and lying between therabbeted edges of two wood facing members secured on the carframe.

Instead of the common door post illus trated, I may use the channel ironpost V, shown in section in Figs. 12, 13. Tothis post the usual beltrail V is secured by a' riveted bracket W and above and below the beltrail wood members V are secured to the post V to receive the externaland internal sheathing X, X. The channel iron post is made wide enoughto project outside the plane of the outer sheathing so that its outerflange V may be engaged by the hook, such as H, at the rear edge of thedoor.

It may be noted that ice is unlikely to interfere with the working ofthe door since the latter rests upon ungrooved rollers and? does notcome into contact with parts surrounding the rollers. I

-What I claim is: I

1. The combination with a freight car, of parallel, oppositely turnedexternal horizontal flanges fixed to the car above and below itsdooropening, respectively, a doorv providednear its upper and lower sides,respectively, with flanges engaging over and under the flanges firstmentioned, respectively, cylindrical door-supporting rollers fixed tothe car below the door and projecting above the outer portions of theirmountings and normally sustaining the weight of the door and maintainingthe flanges out of door-supporting and friction producing con 3cylindrical rollers mounted on the car below the door, projecting aboveadjacent parts extending farther outward from the plane of the door, andin position for carrying practically the entire weight of the door bymaintaining the flanges out of door'supportingand frictional contact attheir horizontal faces.

In testimon' whereof I aiiix my signaturev inpresence 0 two witnesses.
